Honestly I think Hunters will be sorely disappointed with SoD. Unless you really like pre-BC Hunter there’s not a lot to look forward to. It’s mostly just the classic Hunter with the same bad talents, the same baseline class design mistakes, only with fragments of various better iterations of future expansions sprinkled on top. There’s Explosive Shot, for example, but it shares a CD with Arcane Shot (which itself shares a CD with Aimed Shot) and no Lock and Load or any other mechanical integration. So it’s just basically “more damage” with no playstyle difference. You can play without a pet if you want, too. No new role or any real innovation.
Mileyy wrote a good summary of it here.
If people want good Hunter gameplay to look forward to, look to Cata classic and hope the next WoW expansion has meaningful improvements. I doubt there will be any to be found in SoD.
